Percent Change From Baseline at Month 3 in Plasma VEGF Following Intravitreal (IVT) Injection of Anti-VEGF Agent

Percent change in blood VEGF level is calculated as the difference in blood VEGF level measured after 3 month of anti-VEGF agent IVT treatment (Ranibizumab or Aflibercept) when compared to baseline blood VEGF level.

Time frame: Change from baseline at Month 3

Population: Full Analysis Set (FAS): The FAS consisted of all randomized patients who received at least one dose of study treatment. FAS was the analysis set. However, patients who were randomized due to erroneous use of the IRT system and who did not receive at least one dose of study treatment were excluded from the FAS.

Mean Change From Baseline in Best Corrected Visual Acuity (BCVA) of the Study Eye Over Time

BCVA score is assessed on study eye based on the number of letters read correctly on the Early Treatment Diabetic Retinopathy Study (ETDRS)-like visual acuity charts at a testing distance of 4 meters. An increase in score indicates an improvement in acuity. Change from baseline calculated as observed post-baseline value - baseline value.
